The leads plug into the bottom of Optonic Bait Alarms and into the sounder box, allowing you to have the sounder box up to 2.5mtrs away, in a bivvy or on bad banks or were you need your rods separate, also useful in bad weather or noisy conditions. Buy now no more being made. Only a few in stock when they have gone that's its.

Note the sounder box is not included, its there just to show how the leads fit into the sounder box.
